Issue with Gradient Boosting Tree Regressor

[mahmoud_shihab]

I'm currently trying to run a GradientBoostedTree model in a python code recipie as shown below:

# -*- coding: utf-8 -*-
import dataiku
import pandas as pd, numpy as np
from dataiku import pandasutils as pdu
from sklearn.ensemble import GradientBoostingRegressor

# Read recipe inputs
field = dataiku.Dataset("HM_Analysis_FieldLevel_prepared")
field_df = field.get_dataframe()
# GBT_81
model_1 = dataiku.Model("WyoWL843")
pred_1 = model_1.get_predictor()

# GBT_79
model_2 = dataiku.Model("sXriI8AV")
pred_2 = model_2.get_predictor()

data = field_df['Total_diff_sum_sum']<=250
data.head()

# Compute recipe outputs from inputs
# TODO: Replace this part by your actual code that computes the output, as a Pandas dataframe
# NB: DSS also supports other kinds of APIs for reading and writing data. Please see doc.

best_fit_df = field_df # For this sample code, simply copy input to output

# Write recipe outputs
best_fit = dataiku.Dataset("best_fit")
best_fit.write_with_schema(best_fit_df)

However, when I run this, I get the error in the attached picture.

I have the following installed:

ipykernel=4.8.2=py37_0
ipython=7.29.0=py37hb070fc8_0

 What am I doing wrong?

Hi @mahmoud_shihab ,

The current error "ModuleNotFoundError: No module named 'sklearn.ensemble.gradient_boosting'" suggests the import for GradientBoostingClassifier

Not sure why that's happening as a test can you try importing 

import sklearn.ensemble

and let us know if you still see the same error.

Hey Alex,

I have tried that as well.

It seems that (for some reason), it is using sklearn 0.20 as the default way to call the model for the visual recipies...

Not sure how to change that, but after downgrading my sklearn, it worked...

But now I have the issue of figuring out why it wasn't using the sklearn in the environment specified...
